Panini Lens Projection and Post Process buffers broken in 5.5

Development Rendering

Hello! We’ve just moved to 5.5 and noticed the Panini Lens Distortion doesn’t behave the same way (i.e broken) on some buffers (scene depth, custom depth, world normal etc). It’s not an option for us to change the Blendable Location so everything has to be after the Tonemapper. To clarify this all worked fine in 5.3.

In the example below note that the scene depth buffer doesn’t seem to be a affected by the Panini Projection at all anymore, hence the double image. One with lens distortion and one without

Thanks Ben
